Updated information regarding the rating of this examination may be posted on the New York State Education Department s web site during the rating period. Check this web site http://www.emsc.nysed.gov/osa/ and select the link Examination Scoring Information for any recently posted information regarding this examination. This site should be checked before the rating process for this examination begins and several times throughout the Regents examination period.

Directions to the Teacher Follow the procedures below for scoring student answer papers for the Physical Setting/Physics examination. Additional information about scoring is provided in the publication Information for Scoring Regents Examinations in the Sciences. Use only red ink or red pencil in rating Regents papers. Do not attempt to correct the student s work by making insertions or changes of any kind. On the detachable answer sheet for Part A and Part B 1, indicate by means of a checkmark each incorrect or omitted answer. In the box provided at the end of each part, record the number of questions the student answered correctly for that part. Students responses must be scored strictly according to the Scoring Key and Rating Guide. For open-ended questions, credit may be allowed for responses other than those given in the rating guide if the response is a scientifically accurate answer to the question and demonstrates adequate knowledge as indicated by the examples in the rating Fractional credit is not allowed. Only whole-number credit may be given to a response. Units need not be given when the wording of the questions allows such omissions. Raters should enter the scores earned for Part A, Part B 1, Part B, and Part C on the appropriate lines in the box printed on the answer booklet, and then should add these four scores and enter the total in the box labeled Total Written Test Score. Then, the student s raw score on the written test should be converted to a scaled score by using the conversion chart that will be posted on the Department s web site: http://www.emsc.nysed.gov/osa/ on Thursday, January 5, 007. The student s scaled score should be entered in the labeled box on the student s answer booklet. The scaled score is the student s final examination score. All student answer papers that receive a scaled score of 60 through 64 must be scored a second time. For the second scoring, a different committee of teachers may score the student s paper or the original committee may score the paper, except that no teacher may score the same open-ended questions that he/she scored in the first rating of the paper. The school principal is responsible for assuring that the student s final examination score is based on a fair, accurate, and reliable scoring of the student s answer paper. Because scaled scores corresponding to raw scores in the conversion chart may change from one examination to another, it is crucial that for each administration, the conversion chart provided for that administration be used to determine the student s final score.

Please refer to the Department publication Regents Examination in Physical Setting/Physics: Rating Guide for Parts B and C. This publication can be found on the New York State Education Department web site http://www.emsc.nysed.gov/osa/scire/scirearch/phyratg0.pdf. Teachers should become familiar with this guide before rating students papers. Scoring Criteria for Calculations For each question requiring the student to show all calculations, including the equation and substitution with units, apply the following scoring criteria: Allow 1 credit for the equation and substitution of values with units. If the equation and/or substitution with units is not shown, do not allow this credit. Allow 1 credit for the correct answer (number and unit). If the number is given without the unit, do not allow this credit. Penalize a student only once per equation for omitting units. Allow full credit even if the answer is not expressed with the correct number of significant figures. 5 [1] Allow 1 credit for.0 N ± 0. N. Part B 53 [1] Allow 1 credit for constructing the resultant 3.7 cm ± 0. cm long, at an angle of 36 ± from vector B. Examples of 1-credit responses: A R or R B A B Note: Do not deduct credit if the resultant vector is not labeled. 54 [1] Allow 1 credit for 7.4 N ± 0.4 N or an answer that is consistent with the student s responses to questions 5 and 53.

Regents Examination in Physical Setting/Physics January 007 Chart for Converting Total Test Raw Scores to Final Examination Scores (Scaled Scores) The Chart for Determining the Final Examination Score for the January 007 Regents Examination in Physical Setting/Physics will be posted on the Department s web site http://www.emsc.nysed.gov/osa/ on Thursday, January 5, 007. Conversion charts provided for previous administrations of the Regents Examination in Physical Setting/Physics must NOT be used to determine students final scores for this administration. Submitting Teacher Evaluations of the Test to the Department Suggestions and feedback from teachers provide an important contribution to the test development process. The Department provides an online evaluation form for State assessments. It contains spaces for teachers to respond to several specific questions and to make suggestions. Instructions for completing the evaluation form are as follows: 1. Go to www.emsc.nysed.gov/osa/exameval.. Select the test title. 3. Complete the required demographic fields. 4. Complete each evaluation question and provide comments in the space provided. 5. Click the SUBMIT button at the bottom of the page to submit the completed form. [10]
